150 A TIG WELDING MACHINE
TIG150i
INTRODUCTION
The TIG150i is a 150A inverter-style AC/DC TIG welder that is used to weld both ferrous
and non-ferrous metals. The inverter technology is a smaller and therefore lighter package
size allows portability when needed or can also be placed onto a cart for traditional use
around the shop. Welding capabilities range from extremely thin up to 1/4” on multiple
passes. The welder features ease-of-use for quick start-up in addition to multiple features
such as upslope, downslope, pulse and frequency adjustment or the most experienced
welder. Applications include automotive repair, collision repair, motorsports, manufacturing,
marine, aviation, agriculture and metal fabrication shops.

to material before it cools.
• Pulsed arc for working even on thin sheets,
where the heat transferred must be kept to a
minimum.
• Tunnel design construction allowing an
exceptional cooling efficiency, keeping those
components that suffer in dusty environments,
such as electronic circuits, out of the cooling
flow.
• AC balance adjustment or penetration and
tungsten consumption control.
• Adjustable AC Frequency 50 - 150Hz for
precise heat output control.
• Background amperage adjustable from 5 to
150 amps DC and 10 to 150 amps AC.

B C o r D
E Mode key. (Right-hand “down” arrow key.)
When selected, one of the following LEDs
lights:
F, G,
H, L, M, N TIG mode there will always be two LEDs lit:
one indicating HF or striking start mode, the other
continuous or pulse mode in 2 or 4 stage.
F - LED. TIG welding with arc
started
without high
frequency.
To light the arc, press the torch trigger and touch the
tung
sten
electrode to the work piece, then lift it. This move
must
be
quick and decisive (0.3 sec.). Use this process when high
frequency is not permitted.
L – LED TIG welding with arc started with high
frequency.
To light the arc, press the torch trigger: a high
voltage
fr
e
quency pilot spark will light the
ar
c.
G - LED. Continuous 2-stage TIG welding
(manual).
When the torch trigger is pressed, the current begins.
When
the
trig
ger is released, returns to zero. In this position, you
may connect the optional pedal control
acces
sory
(TIGINVFP).
H - LED. Continuous 4-stage TIG welding
(automatic).
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the
tor
ch
trigger
.
M - LED. Pulsed 2-stage TIG welding
(manual).
When the torch trigger is pressed, the current begins.
When
the
trig
ger is released, returns to zero. In this position, you
may connect the optional pedal control
acces
sory

N - LED.
Pulsed
4-stage TIG welding
(Automatic)
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the
tor
ch
trigger
.
The Pulsed welding feature varies the weld current from the
main welding current (Peak Amperage – high heat) and the
second level of welding or base current (Background
Amperage – low heat) levels. The TIG150i has two (2)
different weld settings for the pulse features 2-stage TIG
welding (manual) M – LED or 4-stage TIG welding
(automatic) N - LED.
The Pulse frequency is adjustable from .16 to 250 pulses
per second by selecting the mode U and setting the value
with the knob AA. The duration of total time “on” between
“High heat” and “Low heat” are equal.
“LED T ” – Main welding current (Peak Amperage – high
heat)
This value is usually set somewhat higher than it would
be set for a non-pulsed weld.
“LED V ” – Second level of welding or base current
(Background Amperage – low heat)
This of course would be set lower than Main welding
current. This value cannot be higher than the Main welding
current. Once the base current V is set (a percentage in
respect to the main current is established), so this value will
change automatically when increasing or decreasing the
Main current T .
“LED U ” – Pulse frequency (Pulses per Second .
16 – 250 HZ) Is the number of times per second that the
welding current achieves main welding current (Peak
Amperage – high heat).
Some of the advantages:
• Good Penetration with less heat input to material
“burn through”.
• Less distortion.
• Good control of the pool when welding out of
position.
• Ease of welding thin materials.
• Ease of welding materials of dissimilar thickness.
• Helps weld training.
• Smaller bead profile.
• Smaller heat-affected zone.

P –
SELECTOR (Right Arrow)
When this button is pressed, the LEDs light in
suc
cession:
Q - LED
Current frequency in AC welding (50 - 150 Hz).
Current Frequency Control is enabled only in AC
TIG. Use this control to set the AC frequency
(cycles per second).
Current frequency controls bead width and
directional control. As AC frequency decreases,
weld bead/puddle gets wider. As AC frequency
increases, weld bead/puddle becomes narrower
and the arc becomes more focused. Travel speed
can increase as frequency increases.
R - LED
Wave
balance in AC welding
(balance
= 0; Cleaning
= from 1 to 8, flashing; Penetration = from 1 to 8,
not flashing).
The Wave Balance R feature makes it possible to
vary the half cycles of the square wave when
working in TIG AC when welding aluminum alloys.
The point where the two half-waves meet is zero.
The TIG150i offers 3 positions, Balanced, Cleaning
and Penetration.
Penetration (electrode negative) – is when the
Wave Balance R is set clockwise from the “0”
position with non-flashing numbers between“1 - 8”
on the display Z . This is set to produce the more
time at electrode negative and the minimum time at
electrode positive.
This adds the following benefits:
• Can use higher currents with smaller electrodes.
• Increased penetration at a given amperage and
travel speed.
• Use of smaller gas cup and reduced shielding gas
flow rate.
• Reduced heat input with smaller heat effected zone
and less distortion.
Balanced (zero) – is when the Wave Balance R is
set to “0” position on the display Z . This position is
set to produce equal amounts of time electrode
negative (penetration) and electrode positive ). This
will give you less current absorption, reduced
electrode consumption and an ideal ratio between
the width and depth of the welding bead.
Cleaning (electrode positive) – is when the Wave Balance
R is set counter-clockwise from the “0” position flashing
numbers between “1 - 8” on the display Z . This is set to
produce more time at electrode positive and the minimum
time at electrode negative. This adds the following benefits:
• Removes more surface oxides from the plate but
reduces electrode life.
O – Led Displays the electrode diameter. The choice
of
electr
o
de
diameter ranges from 1mm to 4mm (.040 –
5/32”). Use the knob
AA
to
change the diameter. This
function is active only for AC
TIG
welding.

S - LED
Slope up. This is the time in which the
cur
rent, starting from the minimum,
reaches
the
set current value. (0-10 sec.)
Slope Up can be used to assist in preheating cold material
prior to depositing filler material, or to ensure a soft start on
higher amperage settings.
T - LED
Main welding current. (10-130A in MMA
and
5-
150A in TIG)
V - LED
Second level of welding or base current. This
curr
ent
is always a percentage of the main.
Pulsed 2-stage or Pulsed 4-stage only - Use the
Second level of welding or base current to set
the low current pulse of the weld amperage,
which cools the weld puddle and affects overall
heat input. This current is always a percentage
of main current.
U - LED
Pulse frequency (0.16-250 Hz) The peak and
base times are equal. These pulses and the
base current level -V- between them (called the
Second level of welding ) alternately heat and
cool the molten weld puddle. The combined
effect gives better control of penetration, bead
width, undercutting, and heat input
W - LED
Slope down. This is the time in which the
cur-
rent reaches the minimum value and the
ar
c.
Slope Down should be used while
welding materials that are crack sensitive,
and/or to eliminate the crater at the end
of the weld.
X - LED
Post gas. Adjusts the time gas flows after
welding
ends. (0-30 sec.) Post Gas is required to cool the
tungsten rod and weld puddle, and to prevent
contamination of tungsten and weld. Increase post gas
time if tungsten or welds have a dark appearance.
Note: only those LEDs that refer to the chosen
welding
mode will light; i.e., in continuous TIG welding the LED
U
,
representing the pulse frequency, will not
light.
Each LED indicates the parameter that may be adjusted
by
means of the knob
AA
while the
LED
itself is lit.
Five

after the last variation, the LED involved will shut off;
the
main welding current will be displayed, and the
correspon
ding LED T
lights.

How to Setup the Optional Variable Amperage Foot Pedal or
Remote Finger Amp Control (RAD).
• Using High Frequency Start
• TIG AC Mode
The Foot Pedal allows the welder to remotely control the
amperage from 5 amps minimum to 150 amps maximum
shown on the LED Z display.
Install the Foot Pedal or RAD control plug in the AE
receptacle.
Push the procedure selector switch (Left Hand Down
Arrow). This push-button selects the welding procedure
(MMA or TIG). When selected, one of the following LEDs
lights:
B , C , or D
Then push the Mode Key E
(Right Hand Down Arrow).
When selected, one of the following LEDs lights:
F,G,H,L,M,N. Continue to push the button until the L LED
lights along with the G LED.

DESCRIPTION OF PROTECTIVE DEVICES
Thermal protection
This machine is protected by a temperature probe,
which
prevents the machine from operating if the allowable
tempe
ratures are exceeded. Under these conditions the fan
keeps running and the LED J
lights. The duty cycle of the
welder has been exceeded if the welder overheats.
Duty cycle of a welding power source is the percentage
of a ten minute period that the welder can operate without
causing harm to the welder. Ex. A 60% duty cycle means
that the welder can operate for 6 minutes and should cool
for 4 minutes.
Block Protections
This welding machine is equipped with various safety
devi
ces
that stop the machine before it can suffer damage.
In the event of a malfunction, the letter E may appear
on
the
display Z , followed by a flashing
number:
52 = Start button pressed during
startup.
53 = Start button pressed during thermostat reset. In both
cases, release the start
button.
The machine stop is signaled by the flashing LED J
.
When this occurs, it signals:
1) During the start-up p ha s e, the power status of
the
machine.
2) After the start-up phase, incorrect supply
voltage.
3) With the machine running, that the voltage has fallen
below 118V.
4) With the machine running, that the supply voltage is above
280V.
5) During welding, that the voltage exceeds 300V.
switch, wait 5 seconds, and switch it on again. If the
pr

has
been corrected, the welding machine will begin

again.
NOTE: If the
supply
voltage is below 170V at start-up, no LED
will light and the fan is

TIG WELDER MAINTENANCE
Any maintenance operation must be carried out by qualified
personnel.
GENERAL TIG WELDER MAINTENANCE
In the case of maintenance inside the machine, make sure
that the switch AF is in position "O" and that the power cord
is disconnected from the mains. It is also necessary to
periodically clean the interior of the machine from the
accumulated metal dust, using compressed air.
PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secondary
sides of the machine. Do not allow the wires to come into
contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the original
machine, to prevent a connection from occurring between the
primary and secondary circuits should a wire accidentally
break or be disconnected.
Also mount the screws with geared washers as on the original
machine.
TROUBLESHOOTING/MAINTENANCE
To restore operation, check the voltage.
Then
shut off the AC
